Smicridea (Smicridea) curvipenis

This species, S. (S.) microsaccata, new species, and S. (S.) gransdisaccata, new species, are all closely related on the basis of the presence of apicolateral plates on the phallus. In S. (S.) curvipenis the phallus is sharply angled, but in the other two only gently curved. The apex of the tenth tergum is not upturned in S. (S.) curvipenis, but is apically upturned in the others. The tip of the apical clasper segment is bluntly pointed in S. (S.) curvipenis and S. (S.) grandisaccata, but blunt in S. (S.) microsaccata. The internal pheromone sacs differ in all three, being minute with the anterior pair lost in S. (S.) microsaccata, to about a third of the length of their segment in S. (S.) curvipenis, and finally, almost twice as large as their segment in S. (S.) grandisaccata. The Ecuadorian paratype agrees exactly, including the size of the pheromone sacs, with the Colombian material. I have in addition, a series from east central Peru whose genitalia are absolutely inseparable from those of the type, yet whose pheromone sacs are virtually as long as the segments in which they lie; I am considering at this time that this probabaly represents a distinct species.

ADULT.—Length of forewing, 6–7.5 mm. Color fuscous; forewing fuscous, with apical band reduced to scattered small pale hairs. Male abdomen with 2 pairs of very small internal sacs, each sac about 1/3 length of its segment Male genitalia: Ninth segment with anterior margin slightly produced laterally. Tenth tergite elongate, tip expanded in lateral view, produced and slightly enlarged basad in dorsal aspect. Clasper long, parallel-sided, basal segment surpassing tip of tenth tergite; apical segment terete, tapering to a bluntly pointed apex. Phallus tubular, long; phallotheca with a distinct angle at about 2/3 length; apex with mesally sclerotized ventral and dorsal lips, with a large, ovoid, lateral plate which is displaced laterad as seen in dorsal aspect
